摘　　要：人为作用引起的土壤环境变化是衡量和反映土壤资源与环境质量的标志，它与当前世界关注的全球变化和可持续发展密切相关。本文着重讨论近百年来土壤环境的变化以及未来土壤环境变化的新趋势。通过大量的数据，阐述由于人为作用，上地退化和水土污染问题日益严重。文章还进一步从气候变化、人口压力和大型工程建设等几方面对未来土壤环境的影响进行了预测。最后提出了防治土地退化、水土污染及提高土壤环境质量的对策。Human-induced soil environmental change can be as an indicator of soil resources and environmental quality, and it is related to global changes and sustainable development. This paper focuses on soil environmental change and its tendency. It is pointed out that because of human processes, land degradation and contamination are getting more and more serious. Also, in this paper, soil environmental change is predicated according to climate change, population increment and big engineering projects. Finally, control ways are proposed to cope with land degradation and contamination, as well as to improve soil environmental quality
